Bright-orange traffic cones popped up on Chambers Street yesterday to stop privileged parkers from blocking a main exit off the Brooklyn Bridge.

But right around the corner, motorists with official parking placards continued flouting the rules, leaving their vehicles on sidewalks and at fire hydrants.

A police crackdown on a blocklong stretch of Chambers Street behind City Hall came two days after The Post found eight placard-bearing vehicles left in a “No Stopping” zone that serves as a bridge thoroughfare.
